TWINE-HOLDER.

SPECIFICATION forming part of Letters Patent NO. 787,781, dated April18, 1905. Application filed January 28, 1901- Serial No. 45,184.

T0 at whom it may concern.-

Be it known that I, ERKES ERIK MATSSON, a subject of the King of Swedenand Norway, andaresident of Mora, Sweden, have invented new and usefulImprovements in Twine-Holders, of which the following is a specificationreference being had to the drawings accompanying and forming parthereof.

The present invention relates to improve ments in suchrotarytwine-holders as automatically withdraw by means 'of a spring or thelike any excess of twine pulled out.

The object of my invention is to make possible such a regulation of saidwithdrawal that it will be interrupted when a certain length of twinehangs outside the holder.

The invention consists principally in providing a lever, balance, or thelike through eyes or thelike of which the twine has to pass in beingwithdrawn. Said lever is so pivoted and balanced that as long as thepiece of twine hanging down from the end of the lever weighs down saidend the withdrawal of the twine continues; but as soon as the end oftwine hanging down from the end of the balance is too short to weighdown the said end of the balance the latter turns on its pivots andchecks the rotation of the holder by means of a suitable stopper, brake,or the like, 'so that the withdrawal of the twine ceases.

The invention further consists in the combination and arrangement ofparts hereinafter described and claimed.

In the accompanying drawings a twineholder embodying my invention isshown.

Figure 1 shows the twine-holder in a side view. Fig. 2 shows a verticalsection of said holder on lineAB of Fig. 1, and Fig. 3 a top view ofsame.

The difierent parts of the apparatus are supported on a frame 1, whichis secured, by means of a rod 2, for instance, to the ceiling. Theholder for the ball of twine forms in known manner a rotatable cylinder3, which is provided at the bottom with a central spindle or shaft 1,carried through a spring-box 5, secured to the frame and journaled withits lower end in a foot-bearing 55. The bottom of the said foot-bearingis suitably formed by 5 a ball 6. In the spring-box 5 is placed a spiralspring 61, one end of which is attached to the said shaft, while itsother end is secured to the wall of box 5 in the well-known manner. sidewith 'a flange 7 which keeps the twine wound about the cylinder 3 fromsliding down. The cylinder 3 is, moreover, surrounded by a cylinder 8,secured to the frame 1 and serving to protect the twine wound onto therotary cylinder 3, as well as a support for the twine. For the latterpurpose said cylinder 8 is provided with a hole 19 in the side. Beneaththe cylinder 3 the said frame is provided with a hub or thelike 56 andan eye 12, said eye serving to guide the twine passing through the same.anced beam 9 is journaled, by means of conical pivots 10, in said hub.The said lever 9 is provided on the one end with a weight 11, serving tobalance the beam, and on the other end with an eye 13. Said latter eyealso serves to guide the end of twine which passes through the same. Thelast-mentioned end of said lever 9 is bent at right angle to the lever,and said bent end is passed through a perforation in the end of theframe 1. Attached tothe said balance is an arm 14, which is so arrangedthat in the swinging of the balance the said arm is brought in or out ofthe way of an arm 15, secured to the said rotary holder. To avoidsubjecting the rotary cylinder 3 to too sudden shocks when it is checkedby the arm 14, the arm 15 may be connected with the shaft 4 by means ofa friction-coupling. In the constructive form shown in the drawings thiscoupling consists of two disks of felting 21, between which one end ofthe arm 15 is located, and which are forced against the bottom of theholder by means of a springy collar and nut 16.

The working of the apparatus is as follows: The cylinder or holder 3 isturned so that the said spiral spring is wound up. A ball of twine isthereupon placed in the cylinder or holder 3 and its outer end fastenedto the cylinder-wallfor instance, by means of a clip 17--while its innerend is carried through a hole 18, then through the hole 19 in thestationary cylinder 8, and finally through the eyes 12 and 13 of thebalance 9. The weight A swinging lever or bal The cylinder 3 is providedat the out- 11 is so placed that it will balance, for instance, six feetof the twine hanging down from the eye 18 at the outer end of thebalance 9. Accordingly when this part of the twine falls short of sixfeet the balance by means of its weight 11 will hold the arm 14 in theposition indicated by full-drawn lines, so that the said arm M stands inthe way of the arm 15. The cylinder 3 therefore cannot be set inrotation by the spring 61. On the other hand, when the piece of twinehanging down from the eye 13 exceeds six feet in length the balance 9 isweighted down by the twine so that the arm 14: is held in the positionindicated by dotted lines. The arm 1 1 then is not in the way of arm 15,and consequently the cylinder 3 can be rotated by the spring 61, so asto wind the twine extracted onto the cylinder 3 until the weight 11 canonce more overcome the weight of the twine hanging down from the eye 13.With a view to varying the length of twine to be balanced by the weight11 a shifting weight 20 may be provided on the beam 9 or the weight 11be adjustable.

When a ball of twine has been entirely consumed in the holder 3, the endof it which is still fast in the clip is tied to the inner end of afresh ball. The latter is subsequently placed in the holder and itsouter end introduced in the clip 17 and the apparatus is again ready forcontinued use.

Having now described my invention and how it may be carried out, Iclaim 1. The combination with a twine-holder having a turnable ball-boxfor the twine, and a motor adapted to cause the said ball-box to coilback the extracted twine when released, of a balanced beam adapted tocarry the free end of the twine, and means on said balanced beam forstopping the rotation of the ball-box when the end of twine hanging downfrom the said balanced beam becomes too short to weigh down the end ofthe beam from which it hangs (fiOWl, substantially as and for thepurpose set E2. The combination with a twine-holder having a turnableball-box for the twine, and a motor adapted to cause the said ball-boxto coil back the extracted twine, of a balanced beam adapted to carrythe free end of the twine, means on said balanced beam for stopping therotation of the ball-box when the end of twine hanging down from thesaid balanced beam becomes too short to weigh down the end of the beamfrom which it hangs down, and a weight on said beam, substantially asand for the purpose set forth.

3. In a twine-holder, the combination of, a frame, a cylinder, an axlefor said cylinder journaled in said frame, a spiral spring attached tosaid axle and frame, a balanced beam pivoted to said frame, an eye onsaid beam, an arm extending from said axle, a frictioncoupling on saidaxle adapted to connect one end of said arm to said axle, and an armattached to said beam and adapted to engage with the first-mentionedarm, substantially as and for the purpose set forth.

4. In a twine-holder the combination of, a frame, a cylinder, an axlefor said cylinder journaled in said frame, a spiral spring attached tosaid axle and frame, abalanced beam pivoted to said frame, a weight onsaid balanced beam, an eye on said balanced beam, an arm extending fromsaid axle, a frictioncoupling on said axle adapted to connect the saidarm to said axle, and an arm attached to said balanced beam and adaptedto engage with the first-mentioned arm, substantially as and for thepurpose set forth.

In testimony whereof Ihave signed my name to this specification inpresence of two subscribing witnesses.
